What is BS EN 61439-2:2018?

BS EN 61439-2:2018 is a technical standard that sets out the requirements for low voltage switchgear and controlgear assemblies. It specifies the design principles, constructional features, and performance characteristics of these assemblies.

The Key Requirements

One of the key requirements of BS EN 61439-2:2018 is that switchgear and controlgear assemblies must have defined short-circuit withstand capabilities. This means that they should be able to withstand the thermal and dynamic effects of a short-circuit fault without sustaining significant damage.

Additionally, this standard requires that assembly manufacturers provide clear instructions on the maintenance and operation of their products. This ensures that end-users can safely operate and maintain the assemblies to achieve their intended performance.

Testing and Verification

BS EN 61439-2:2018 also outlines the testing and verification procedures that manufacturers must follow to ensure compliance with the standard. These procedures include type testing and routine verification. Type testing involves subjecting the assemblies to various electrical and mechanical tests to assess their performance under different operating conditions.

Routine verification, on the other hand, is carried out to ensure that the manufactured assemblies are consistent with the design and meet the required specifications. This involves visual inspections, measurement checks, and assessment of the assembly's environmental suitability.

Benefits and Importance

BS EN 61439-2:2018 plays a crucial role in promoting safety, reliability, and performance in low voltage switchgear and controlgear assemblies. By adhering to this standard, manufacturers can ensure that their products are designed and constructed to withstand electrical faults and operate efficiently.

Compliance with BS EN 61439-2:2018 also provides reassurance to end-users that the assemblies meet high-quality standards and can be safely operated and maintained. This helps prevent accidents, downtime, and expensive repairs or replacements.

Furthermore, BS EN 61439-2:2018 serves as a benchmark for the industry, allowing manufacturers to compare their products against standardized criteria. It promotes fair competition and enables customers to make informed decisions when selecting switchgear and controlgear assemblies.
